Abstract

The present invention relates to a digital movie program package and key transmission system and method, comprising: connecting a program source system and a movie server through a network transmission medium; program source parameters and send them to the second control module; retrieve the pre-stored program source parameters from the internal storage medium; judge whether the first program source parameters and the second program source parameters are repeated with the pre-stored program source parameters; , re-call, if not repeated, then call the first program source and the second program source from the internal storage module and the external storage module, and send to the second control module; call the API in the movie server to send Integrity check is performed on the first program source and the second program source in the second control module. The invention can solve the disadvantages of complex parameter configuration, unfriendly operation method, distance limitation and inability to complete playable verification of remote transmission files in the traditional method.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a digital movie program package and a key transmission system and method. Background technique [0002] At present, there are several ways for the transmission of digital movie program packages and secret keys: First, the digital copy is physically connected to the movie server (IMB) through the USB interface, and the DCP content is loaded into the IMB through the content management interface on the IMB software. Store and verify, but this transmission method is limited by the operating distance and needs to be completed in the near field next to the projection equipment. Second, the digital copy is preloaded into the program library (disk storage) of the theater TMS system, and then the TMS system transmits the program to the movie server (IMB). The digital copy is physically connected to the theater TMS system through the USB interface. The content management interface on the ...
